Given a situation where an object is dropped at a certain height, how should the net force equation be written considering the fact that only gravity and drag acts on it? I'm stuck on whether the equation is written like this:
[tex]\Sigma F = F_{g} - F_{d}[/tex]
Or like this because g is negative?:
[tex]\Sigma F = -F_{g} + F_{d}[/tex]
[tex]\Sigma F = F_{g} - F_{d}[/tex]
Or like this because g is negative?:
[tex]\Sigma F = -F_{g} + F_{d}[/tex]
